Application filed'April 14, 1911. Serial No. 621,130.

7 To all whom it may concern:

Be it known that I, JOHN A. HILL, a cititageously used in connectionwith a boiler for quickly heating water prior to entering the boiler.

Another object of the invention is to provide a hot water heater havingcoils of tubing arranged above a burner whereby the coils can bethoroughly heated with a minimum expenditure of fuel.

A further object of the invention is to provide a heater of the abovetype consisting of comparatively few parts easily assembled, durable andefficient for the purposes for which they are intended.

I attain the above objects by a mechanical construction that will behereinafter specifically described and then claimed and reference willnow be had to the drawing, wherein Figure 1 is a vertical sectional viewof the heater, Fig. 2 is a horizontal sectional view taken on the lineXX, Fig. 3 is a perspective view of a detached clamping band. Fig. 1 isa perspective view of a detached burner support, and Fig. 5 is adiagrammatical view showing the adaptation of the device in connectionwith a boiler.

The reference numeral '1 denotesa pipe adapted to be connected to awater boiler or receptacle, said pipe having a central partition 2. Thepipe 1 below and above the partition 2 is provided with bosses 3 and 4having openings adapted 'to receive the upper and lower ends 5 and 6respectively of coils of tubing 7 and 8, the coil of tubing 7 beingarranged within the convolutions of the coil of tubing 8, whereby thecoils of tubing will occupy a comparatively small space and bafile aflame that passes upwardly from the lower convolutions of said coils.The lower end of the pipe v1 is adapted to admit cold water to the lowerconvolutions of the coils 7 and 8, and as the water is heated withinsaid coils it passes 7 into the upper end of the pipe 1 and is discharged into a water boiler or receptacle in communication with saidpipe. The partition 2 in the pipe 1 separates the hot water from thecold water or in other words, itprevents the commingling of the hotwater with the cold water.

To confine the heat of a flame in proximity' to the coils 7 and 8, saidcoils are incased by a cylindrical vertical shell 9, preferably made ofa single sheet of metal bent to a cylindrical form with the meetingedges thereof cut away, as at 10 to provide clearance for the ends 5 and6 of the coils 7 and 8 respectively.

The shell 9 is maintained in a cylindrical form by metallic bands orstraps l1, each strap having one end thereof providedwith an opening orslot 12 to receive a malleable tongue carried by the opposite end ofsaid strap, said tongue being inserted in the opening 12 and bent tolock the strap in engagement with the outer sides of the shell 9. Fittedupon the upper end of the shell is a cap 14 having an exhaust pipe 15,and this cap is adapted to assist in confining the heat around the coils7 and 8. Riveted or otherwise mounted, as at 16 in the lower end of theshell 9 is a bracket 17 having a bifurcated lateral support 18 foraburner 19. This burner is of the ordinary and wellknown type and isadapted to receive a supply of artificial or natural gas from a suitablesource.

The coils of tubing 7 and 8 are of a small diameter and a sufficientnumber of convolutions are used whereby the water passing in the lowerends of the coils will be thoroughly heated before passing out of theupper ends of the coils. The arrangement of the coils baffles the flameof the burner 19 and retards the heat units sufiiciently to insure athorough heating of the coils.

What I claim is A water heater comprising a verticallydisposed pipeprovided with an integral partition to provide a cold water and a hotwater section, said cold water adapted to communicate with the sourcesof supply and said hot water sec-tion adapted to communicate with theboiler, a pair of coils of tubing having the upper convolutions thereofconnected with the hot water section one above the other, the lowerconvolutions of. said pair of coils connected section with said coldwater section one above the said shell, and a burner carried by saidsup- 10 other, a vertically-disposed cylindrical shell port.

inclosing said coils of tubing and from In testimony whereof I aflix mysignature which extend the ends of said coils, said in the presence oftwo witnesses.

' pipe disposed in parallelism with respect to JOHN A HILL.

said shell said shell having its lower end open, a cap mounted upon theupper end of Witnesses:

said shell and having an exhaust opening, Jos. Gr. BEALE,

a gas burner support at the lower end of MILDRED K. BOLAR.
